What are Brute Wyverns?

Brute Wyverns (Japanese 獣竜種) are a class of monsters first introduced in the third generation. This class is considered to be Wyverns that are adapted to complete life on land, even sometimes being called Theropods from greatly resembling some predatory dinosaurs. These monsters are typically large, bipedal theropods, that are prone to living in areas abundant in food sources. Brute Wyverns exhibit a wide variety of dietary habits; some are strictly herbivorous or carnivorous, while others subsist on insects or even minerals. These monsters often use their heavy, muscular bodies to charge blindly through an environment to damage attackers or prey, and include many defensive adaptations, including tail clubs, horns, and even hammer-like chins and fists. Like most classes, Brute Wyverns can be found in almost any type of environment.

List of Monsters in this Class


  • Barroth is a Brute Wyvern found living in the Sandy Plains.
  • Like other Brute Wyverns, its physique is similar to the Flying Wyverns.
  • Barroth feed on Altaroth and other insects.
  • Gets the title, Landslide Wyvern, from its behavior of using mud.
  • The territories of Barroth are usually bogs or oases. In their territory, they are usually hidden under the mud.
  • The crown of Barroth is its nostrils. While under the mud, it just uses the crown to breath like a tube. When angered, it is known to breath harder, making it seem like steam is coming out of its crown.
    • This crown is extremely tough, making it hard for most cutting weapons to even cut into it, though blunt weapons have proven to be quite effective against Barroth.
  • The fertile mud keeps the Barroth cool, from the intense heat of the desert, and also protects it from parasites. From this mud, it protects it from taking fire damage but water can wash the mud off easily.
  • The front limbs of Barroth are mostly useless for fighting. So the limbs are used for helping it dig.
  • Barroth have bad attitudes, like most Brute Wyverns. Its known to hate having its bog crowded by a bunch of creatures, it especially hates when another large monster enters its territory. If a large monster is in its territory, it will face the threat and fight it, either killing or injuring the threat.
    • Barroth have even been seen fighting and defeating Rathian.
  • Generally, it uses its brute force and speed to attack threats. It will also shake mud off its body.
    • Its been proven that a Barroth's charge can destroy whole ant hills in just one charge or even send large objects in the air such as boulders and Great Jaggi.
  • During the mating season, male Barroth will head-butt each other in order to keep or gain a larger territory, so they can mate with female Barroth. The larger the bog or oases, the more female Barroth that will go into it. Male Barroth must also use their crown to attract mates and keep the mud well adhered on their body. If any mud or dirt is in their crown, they will rub their head on the ground.
  • Male Barroth have larger head crowns than female Barroth.
  • Female Barroth will lay up to ten or more eggs. It is unknown what the birthing method and the birthing grounds of the Barroth is of wild Barroth.
  • Young Barroth will not leave the bog or oasis until they grow a bit more. While growing, they will feed on insects around the area.
  • The tail of Barroth is a favorite dish.
  • The shell of a Barroth is always covered in mud, always hard either way with or without mud on it. The cortex has multiple layers of mud from many years, making the shell very hard.
  • The fertile mud from Barroth is good for crops.
  • During hotter months in the Sandy Plains, Barroth are known to move to the cooler Deserted Island.

Jade Barroth

  • Jade Barroth is a Subspecies of Barroth.
  • It has a larger crown than its desert cousins.
  • It gets the title, Ice Crushing Wyvern, from its head being able to crack the frozen ice.
  • Like Barroth, it feeds on insects and Neopterons such as Bnahabra.
  • Unlike Barroth, Jade Barroth wears ice and snow on its body by secreting a special mucus known as Frozen Glob. It solidifies once mixed with snow or ice. This mucus can be produced around the tail of some Jade Barroth, covering potential threats in freezing ice.
  • Jade Barroth is considered to be a living avalanche from how fast it can run.
  • Jade Barroth are seemingly smarter than Barroth yet also more aggressive. They've been seen to charge more wildly, send snowballs flying at threats in front of them, and even cracking the very ground with their crowns.
  • Just like Barroth, Jade Barroth's tail is a favorite dish.
  • The claws of Jade Barroth can cause frostbite with just a touch. With some older Jade Barroth, the claws can actually cause severe pain to them as well.
  • The Jade Barroth's cortex is just profound.


  • Uragaan doesn't just use its chin like a hammer but they also use it like a shovel to dig underground and possibly to pick up ore. The chin has evolved to crush ore, rocks, and other minerals and to break them off walls or other objects. They also use their chins against threats and to fight for territory.
  • To try to scare of threats, it'll roar and smash its chin multiple times.
  • Besides their tail, their chin help them keep balance.
  • When they are young, they are herbivores and as they get older, they switch to eating ore.
  • To keep cool, they will release the gas from their body as both a means of keeping cool and for defense. When enraged, the gas is hotter and changes to a flammable gas.
  • Uragaan usually rest in or on top of brown liquid oil. As a result, their tails and stomachs are usually covered in it. The oil bonds Uragaan's body with rocks, which can act as a protection against degradation of its own shell when rolling. The rocks it carries can either be used later as food or thrown as a weapon when they feel threatened.
  • It is difficult to determine a Uragaan's sex from appearance alone. However, during breeding seasons, the males will dress itself with many rocks to impress the females. Diet during this season consists of high quality minerals and valuable jewels to obtain a hard, glossy, golden shell and jewel covered body. The males compete for the brightest display.
  • Its sleeping gas comes from remains of food its eaten.
  • They're able to withstand the heat of lava and protect their internal organs with their heat-resistant shell.
  • The rubies found on some Uragaan are actually special ore.

A Hunter Named Uragaan

  • Uragaan is considered to be a tragic monster due to it once being a noble hunter from Yukumo Village. He was considered a hero among villagers in the region.
  • One day he journeyed to a new place, but got sidetracked due to a Felyne being in danger at the hellish volcano. He went to the volcano to help the Felyne, but ended up being trapped within that fiery prison.
  • He asked for the Hunter’s Guild assistance, but they said it would be too dangerous to try to rescue him and left for him dead. This caused Uragaan to hate the Hunter’s Guild for all eternity.
  • Though he was left alone in the volcano, he didn’t actually die immediately. Overtime, the volcano slowly changed him into something else... He changed into something that wasn’t human anymore before he eventually killed himself.
  • Uragaan pledged revenge against the Guild due to them allowing him to suffer and change into a hideous beast. His spirit now roams the volcano as a disheartened beast.

Crystalbeard Uragaan

  • "For years, in various volcanic regions, miners spoke about a monster known as Crystalbeard. This monster was said to have extremely rare, valuable jewels, and other treasures, on it, making it a walking gold mine waiting to be found. All who searched for this monster usually ended up being smashed by its treasure-covered chin, for letting greed get the best of them."
  • Uragaan usually rest in or on top of brown liquid oil. As a result, their tails and stomachs are usually covered in it. Crystalbeard Uragaan lives in rare areas where this liquid oil has dissolved special minerals inside of it. By resting in this stuff, Treasure Nuggets have crystallized on its chin and tail.
  • Due to this special ore being a staple food in its environment, Crystalbeard Uragaan has a darker appearance.
  • When Crystalbeard Uragaan rolls at foes, it'll actually send these rocks flying at foes out of its range.
  • Unlike Steel Uragaan's rocks, some of Crystalbeard Uragaan's beautiful ores have a sleepy effect to them, knocking potential predators out.
  • Compared to normal Uragaan, Crystalbeard Uragaan are more destructive with their chin slams.
  • According to an interview, they wanted to give Crystalbeard a different appearance that reflected its beauty, a treasure kind of way. They wanted to keep its concept like the other Deviants, however, Capcom added an additional theme to this monster: Getting rich!.
    • It is suggested that they wanted this to be a variant of Uragaan at first, but instead made it a Deviant due to wanting it to be a real threat despite its strange mechanic.
  • In the end, Crystalbeard Uragaan was given the ability to throw mineable ores, alongside being able to mine it, to make it different enough from the other Deviants.

Steel Uragaan

  • The Steel Uragaan is a subspecies of Uragaan.
  • Its feeding habits are different from other Uragaan species. Steel Uragaan is known to feed on sulfide minerals. The gas in the minerals give it its strong smell and this smell even effects the explosive rocks its throws, giving them both explosive and smelly effects.
  • The gas has affected its color, giving it a blue coloration from both oxidation and sulfur gas.
  • Steel Uragaan are confirmed to live in and form herds. Steel Uragaan do this so they can secure an area for its ore deposits and other foods.
    • These herds can cause many earthquakes together, making a number of problems for nearby villages.
  • The Steel Uragaan's chin is said to hold large amounts of heat. By slamming its chin, its able to maintain the heat in its body.
  • The Steel Uragaan's scales have higher strengths from their chemical change.


  • Duramboros gets the title, Hammer Tail Wyvern, from obviously their tail.
  • When Duramboros are sleeping or just lying down, they can easily be mistaken for a large mound or hill.
  • Trees are Duramboros's staple diet. They use their tail to knock down trees in order to feed on them, which is the reason why they evolved this hammer-like tail. Most fallen trees found in areas are actually caused by Duramboros. They also use their tail for defense against threats and will use their tail in more ways to help them fight threats, such as spinning around in a circle. The only downside is that Duramboros take a long time to recover after some attacks, making them highly vulnerable to a counter attack from threats.
  • As the Dumramboros grow, the new tail shell moves outward and pushes the old away.
  • Duramboros are very territorial to a point where if anything carelessly approaches them, they will attack and possibly even kill that creature without warning. It is actually a lot more aggressive than most predatory Brute Wyverns.
  • Its shell is incomparably thick and cannot be damaged by ordinary monsters. On its shell are moss and mushrooms, which that grow on it. It is theorized that they use this to retain moisture and warmth, but the moss actually serves as a shock absorber for older Duramboros. The mushrooms and moss are also said to serve as food if they aren't able to find any food.
  • Their humps store nutrients and fat, which they can burn a lot of when enraged so they can move faster and attack more violently.
  • Duramboros's horns are wider than a man's chest. These horns are used to intimidate and charge at threats.
  • Duramboros are oviparous so they lay eggs. Female Duramboros live in herds and guard their nests from predators, while male Duramboros live alone. While young, males live alone not to far away from the herd as they grow up.
    • Interestingly, most of the Duramboros we hunt are almost always male.
  • During the winter, Duramboros dig underground to hibernate and use their humps to survive through it. It is said during the fall, that Duramboros will eat just about anything to survive the winter, including some man-made objects made of wood.
  • The mushrooms and humps from Duramboros are a delicacy to hunters, though the Guild rarely get request to hunt them for that reason.
  • Due to constant pounding its tailbone has worn into a spherical shape.

Rust Duramboros

  • Rust Duramboros are a Subspecies of Duramboros and considered to be the largest known Brute Wyvern species.
  • Rust Duramaboros are a lot more aggressive than typical Duramboros and can even take on Black Diablos.
  • Sand and ore doesn't completely change its color to its arid look, a lot of it also comes from the blood of monsters that attacked it and ended up dying from it. Rust Duramboros is covered in the blood of monsters that attempted to hunt or kill it, but failed to before being killed by Rust Duramboros. They will even kill some harmless herbivores.
  • The copper-stained moss on Rust Duramboros can weaken an opponent's attacks.
  • Its Axe-like Tail is used to knock sand at threats and is more so a weapon instead of a tool.
  • Many Rust Duramboros have been seen within the Sandy Plains with different colors from each other. It is believed that the different colors might be due to them living in different parts of the Sandy Plains.


  • In ancient times, Gasurabazura's ancestors were aquatic in nature and lived in the White Lake. The area had many lakes and rivers before the long droughts began. Due to the droughts, Gasurabazura's ancestors eventually became a terrestrial species.
    • The fins found on their body are remnants of their ancestors.
  • Gasurabazura are usually quite quiet but this is false. Gasurabazura actually have a Savage Nature when angered. When greatly angered by a threat Gasurabazura will pump blood into its fins, arms, and tail, expanding those parts in size. To help pump blood into those areas of its body, Gasurabazura has powerful lungs that once aided its ancestors in their aquatic environment.
    • Strangely, the blood of Gasurabazura is always hot and its body parts are expanded by this heat.
  • Gasurabazura mainly feeds on Kusubami due to it extracting the poisons this particular prey uses for defense. This poison drips from its body from it ingesting and absorbing the poisons from the Kusubami for a long time.
  • On Gasurabazura's body are remnants of fins once aiding its ancestor in swimming but are now used for intimidating potential threats.
  • Dripping from the gaps of its scales are powerful poisons gathered from its prey. These scales not only drip poison but aid in producing more poison for some of its attacks. This means that some of the poisonous attacks maybe much larger than many would expect.
    • Its teeth also contains poison, allowing it to deliver a poisonous bite.
  • Gasurabazura's skin is just about as white as the sand in its environment, giving it better camouflage in its environment. For some stronger individuals, this skin doesn't take damage easily.
  • When its tail is expanded with blood, Gasurabazura is able to smash prey with its tail easily.
  • Similar to Brachydios, Gasurabazura is able to use its arms to attack and fight enemies, leaving behind bits of poison while attacking enemies though only when angered. It is also able to take advantage of its powerful arms and use them to toss sand or debris at its enemies or even use them to make sand traps for its enemies.


  • Brachydios is a very recently discovered Brute Wyvern and the only known of the Forefoot Fist Wyverns.
  • Some of the Brachydios's hide is made of Obsidian that melted on the shell and has combined with not just the shell, but also the Slime Mold.
  • Brachydios are primarily seen in volcanoes, but occasionally are seen in forests and ice-covered areas.
    • They've recently been seen in the Old World as well.
  • Brachydios are known to steal territories from other large predatory monsters and even kill them to steal their territory.
  • Brachydios are carnivorous and feed on many different types of herbivores.
    • Brachydios also sometimes feed on ore.
  • Brachydios's arms evolution is quite different from other known Wyvern species since they didn't evolve into wings or into feet. Everything, such as its claws on its arms, have degenerated and now is just a Pounder. The Brachydios's fist can't even cut through objects.
  • Brachydios is considered to be the most agile known Brute Wyvern thus far. It has a lot more strength in its legs compared to other known Brute Wyvern.
  • Its Slime Mold forms a special bond with it. Its horn holds a supply of it and this Mystery Slime or Glowing Slime is explosive and can be activated by Brachydios from something in its saliva and horn. It reacts to Brachydios when it becomes enraged and will explode on impact, spreading spores instantly. As it explodes, spores go into the air and land on to Brachydios, growing into the Slime Mold. This Slime Mold grows all over Brachydios's body.
    • The Slime Mold is able to actually travel across the land instead of being stuck in one place.
    • The Slime Mold on each Brachydios is different from the other and larger Brachydios are known to go on rampages from this mold constantly breeding on them.
  • Its title, Crushing Wyvern, comes from the exploding slime mold.
  • Young Brachydios live within the territory of their parents, but the parents don't ever interact with their young. They gather the Slime Molds their parents leave behind, though many of the young die from the explosions of the slime mold due to their shells being underdeveloped. Their shell will also melt from the explosions, which helps them pick up ore that makes their shell stronger and melts onto their shell.
  • The bone marrow of a Brachydios is sticky.
  • Its shell may contain weird bacteria so be careful!
  • Older Brachydios' Pounders are made of iron.
  • The tail also has explosive slime on it.

Raging Brachydios

  • When the Guild were looking through some ancient documents left behind by the Ancient Civilization, they found a particular document that caught their eye. This document showed that Brachydios have been known about for a very long time, while the Guild have only very recently discovered the Brachydios species. This document also talked about some unusual Brachydios that were seen nicknamed the Raging Dual Arms. The Guild took part of this nickname and now call these individuals the Raging Brachydios.
  • It is theorized that Raging Brachydios are Brachydios individuals that have grown isolated in special environments.
  • Usually, the slime mold is living in harmony with Brachydios. Both spreading spores and exploding at the same time, but if the slime mold remains dormant on a surface even after exploding, and something like crustal movement or eruptions happens, than the long dormant slime mold becomes active again. This long dormant slime mold has accumulated power while being dormant and has massive explosive power. This special slime mold is used for sex appeal, showing off a Brachydios's strength. This slime mold is the reason why some Brachydios go to or visit the Ingle Isle. Powerful individuals that gain this new powerful explosive slime become Raging Brachydios and this slime mold seems to be related to the reason why those Brachydios get so big.
    • It is a gamble to get this special slime mold due to it having the potential of killing the Brachydios easily. So it is limited to only a few strong Brachydios individuals.
  • This special slime mold is only able to breed in the Ingle Isle, or other special environments, so Raging Brachydios are only limited to those areas. This slime mold is different due to the higher temperatures and high pressure of Ingle Isle. This is also the reason why Raging Brachydios's shell is a more greenish color, even without the slime on it.
    • It is unknown and unanswered how they get to Ingle Isle, but it is theorized that they may travel distances to get there. Another theory is that they instinctively go there when they reach a set age.
  • Unlike normal Brachydios, these extremely rare Brachydios are noticeably covered in the slime mold on some parts of their body, such as the tail, head, and back.
    • With normal individuals the slime mold on some parts aren't active due to adhesive in their salvia not activating the slime on it, however, the slime mold can be found all over a Brachydios's body.
    • The Raging Brachydios's slime mold is known as Explosive Slime.
  • The slime mold of a Critical Brachydios actually glows in pure darkness and reacts to impact taken from enemies by exploding over time.
  • The Raging Brachydios noticeably has a unique organ known as a Immortal Core. This organ has a special relationship with the slime mold, along with helping the Brachydios live longer. This organ is the reason why the slime mold is so active, compared to normal Brachydios, making its attacks more powerful and making the slime mold breed more rapidly than before.
  • The fist of a Raging Brachydios is called a Brach Destructive Fist. This fist allows it to perform violent attacks.


  • Giaorugu actually comes from the New World.
  • Giaorugu can adapt to any environment, like Abiorugu, and can even eventually become Abiorugu overtime, but they can only be found in the Polar Sea.
    • Giaorugu is Abiorugu's ancestor.
  • Similar to Anorupatisu, Giaorugu hunts for fat-bodied prey to keep itself warm though its body temperature is higher than most other monsters in the Polar Sea.
  • Its bone plates freeze due to its own blood freezing with air contact.
  • Like Abiorugu, Giaorugu prefers to fight enemies at close range.
  • From living in the Polar Sea, most of its attacks involve it using ice and snow.
  • When it freezes its tail, the range of its tail is increased.
    • It seems its own blood might be involved in making the icy blade.
  • The Giaorugu's fangs can freeze the blood of prey, just by piercing the skin.
  • Its scales are extremely hard to scratch.
  • Giaorugu's skin is good for keeping heat in its body, making it perfectly adapted to survive in the Polar Sea.
  • Its frill is extremely tough to gain and not easy to make equipment out of.

Zenith Giaorugu

  • Zenith Giaorugu has further developed its tail in order to store additional fat. This means it can survive without eating for longer periods of time.
    • Food is hard to come by in the Polar Sea.
  • Due to the new shape of its tail, Zenith Giaorugu is able to shatter ice more easily than before. This shows that its giant tail is a powerful weapon.
  • The plates on its back are more blade-like in nature, allowing them to cut through ice easily.
    • When greatly angered, its plates are known to become more red in color.
  • Zenith Giaorugu has learnt how to use and produce cold air. It can freeze prey in its tracks before finishing the defenseless creature off.


  • Abiorugu have very recently came to the Old World. This species is an invasive species from the New World.
    • It is suggested that Abiorugu are still changing in some areas.

  • Its main weapons are its tail and its jaws with its sharp fangs.
  • They have a lot of muscles in their legs, allowing them to pounce on top of prey from far distances.
  • The bone plates on their back are used to keep them both warm and cool. It can both take in heat and release heat from these plates, allowing it to maintain its body temperature. When enraged, muscles will raise themselves and the plates will turn red from the expansion of blood vessels. They aren't intended to show off, they are used to increase its power and its performance in battle. They also vary depending on its mood in battle. From increased blood flow, some parts of its body become weaker to attacks, especially its legs.
    • They are extremely adaptable and can be found in all sorts of different environments like the Jungle and Snowy Mountains.
  • It will constantly drool digestive juices with high acidity to take on armored prey.
  • Abiorugu mostly hunt during the day, but will occasionally hunt at night for sleeping prey.
  • Their scales are very strong and very robust.
  • The bones of Abiorugu have high durability.
  • Its fangs are strong, allowing it to rip apart and slaughter prey.
  • Its tail can potentially slice prey in half with a single powerful smash.
  • An Abiorugu's blood is said to be scarlet in color. This particular blood is called Hot Blood.


  • Glavenus is a recently discovered species of Brute Wyvern found living in the Jurassic Frontier.
    • They've also be sighted in volcanic regions and desert regions.
  • It gets the title, Cutting Wyvern, from its huge blade-like tail.
  • Glavenus is a predator that doesn't let its prey run away or escape easily.
  • Similar to Brachydios, Glavenus is able to jump quite well.
    • On the back of its legs are two claws used to support its weight as it lands.
  • Inside of Glavenus's body is a special fire sac different from other fire sacs. This fire sac allows Glavenus to hold fire in its throat, allowing it to burn prey with its powerful bites. This fire sac also allows Glavenus to breath some usual fiery projectiles at prey. These projectiles can explode on contact though can be left to detonate on their own, while on the ground.
    • When this fire sac heats up greatly, Glavenus's spikes and some other parts will turn red as they smoke with heat.
  • Glavenus's most unique feature is its blade-like tail. The blade-like tail is used in many ways by Glavenus, such as keeping Glavenus's whole body balanced, but its primary use is for attacking. This tail can cut prey in two with a single slash, crack the ground easily, and even block some attacks.
  • Glavenus's tail is made up of many pyroclastic materials, such as ore. By rubbing or dragging its tail on the ground violently, it actually heats up its tail greatly. While its tail is heated up, its tail swings send burst of fire, making its already deadly tail more deadly.
    • While heated up, its tail can slice through prey like butter.
  • Though its tail is more deadly while heated up, Glavenus's tail actually becomes duller at a quicker rate. When a Glavenus's tail is heated, the tail actually becomes more vulnerable to attacks from threats. To solve this problem, Glavenus has evolved a unique behavior. It will actually put its tail in its mouth, between four specially designed fangs, before slowly sharpening its blade-like tail. This restores the tail's sharpness and makes it brand new again, ready to be used in another battle.
    • The hard shell covering Glavenus face protects its eyes from sparks, as it sharpens its tail.
  • When Glavenus sharpens its tail, it is removing soot and ore from its tail and swallowing it. The swallowed soot and ore is accumulated into its special fire sac, where it changes to a semisolid form that is similar to boiling lava.
  • To scare away potential threats, Glavenus will drag its tail on the ground and roar at the foe.
    • By dragging its tail, it shows the threat that it uses fire as a weapon.
  • Glavenus is considered to be one of the smartest known Brute Wyvern species to the Hunter's Guild. This is from its behavior and some of its characteristics.
    • Like other Brute Wyverns, Glavenus is extremely aggressive.
  • Glavenus is considered to be the strongest Brute Wyvern known from its dangerous, skilled fighting style.
  • Glavenus concept was a Land-Based Rathalos.
  • Glavenus is the leader of the Fated Four.
  • It is nicknamed the Burning Blade from its heated tail.
  • Its shell symbolizes its violent, fiery temper.
    • Some shells from older Glavenus have battle scars.
  • Rarely, a crimson-colored gem is produced inside its fire sac. This gem is said to contain the screams of burning souls.
  • Its scales are fragile yet have good resistance against heat and fire.
  • The tail can't be processed by craftsmen by any normal means.
  • The fangs of older Glavenus is capable of cutting a hunter in two without even losing its sharpness.
  • Glavenus: Glavenus' japanese name (Dinovaldo) is a combination of Dinosaur (恐竜), Nova (ノバ), and Halberd (ハルベルド).
  • While in the Jurassic Frontier was in development, the developers were working on a dinosaur-like monster to put into that area.
  • In the middle of the development before the Jurassic Frontier, another concept was thought up, a Tail Blade (尻尾が剣).
  • Eventually, fire was added to the concept of the tail plus the idea of a Fiery Tornado (火災旋風).
  • To make Glavenus different from other monsters, the developers chose to give its tail three phases; Sharpened, Heated, and Dull.
  • Its overall design was to give it the appearance of a glimmering flame.
  • The design of Glavenus's equipment was to give it a harsh look, unlike the Rathalos's equipment, with violent fire.

Hellblade Glavenus

  • Hellblade Glavenus is a giant among the Glavenus.
  • It is said to be able to incinerate everything around it in the blink of an eye. From this, the Hunter's Guild consider Hellblade Glavenus to be equal in destruction to Rajang and Deviljho, making it an Elder Dragon-Level Monster.
  • From it constantly sharpening its tail, Hellblade Glavenus's appearance has changed. Its shell has become discolored from this, along with its eyes, giving it this look like it is always in Rage Mode.
    • Pieces of this shell is highly explosive if carelessly handled.
  • Due to Hellblade Glavenus's constant tail sharpening, it has taken in extreme amounts of rich soot into its body, which has made its fire stronger and explosive. This rich soot is said to be balanced in his body, at least in theory to the Guild.
  • Helllade Glavenus's fire sac is different from a normal Glavenus's fire sac. It not only produces fire but also a strange explosive powder.
  • Not only fire is found in its mouth, portions of this explosive powder is found in it as well. Hellblade Glavenus will not only add fire to its blade-like tail, as it sharpens it, but will also add this explosive powder. This gives its tail fiery heat and powerful explosive blast all in one strike.
    • Though this is a powerful weapon, its tail is now more vulnerable, even when it sharpens it.
  • With destructive power like this, Hellblade Glavenus can both blow enemies sky high and incinerate them with explosive flames.
    • This is how it got its burnt up name, Hellblade.
  • Hellblade Glavenus's tail is longer than a normal Glavenus's tail.
  • Its projectiles are said to be able to destroy rock.
  • Hellblade Glavenus's tail is said to be able to turn a whole mountain to ash.
  • The shell and scales are highly explosive if not handled with care. If it explodes, it engulfs those in explosive fire.


  • A huge Brute Wyvern species that constantly wanders from one area to another, looking for prey. There are features and characteristics that gave the Deviljho a very brute character, and also because of these traits, it was given the title Violent Wyvern. It was also reported that it can prey the creatures around the region to extinction.
    • From Deviljho constantly needing to feed, the Guild sometimes sends hunters to slay them when populations of some monsters begin to decrease quickly in some areas.
  • Deviljho has a huge appetite . It will eat all sorts of creatures like Bird Wyverns, Herbivores, and even some large predatory monsters.
  • Because of its high metabolism and body heat, Deviljho is in constant search for a food source leading it to a nomadic lifestyle.
